Abstract

707,749. Controllers. SMITHS JACKING SYSTEMS, Ltd. May 16, 1952 [June 8, 1951], No. 13647/51. Class 38(3) [Also in Groups XXIX and XXXV] An electrical control system for the control of hydraulic circuits comprising a pump 20 operated by a direct current electric motor wherein a solenoid winding 24 operating an electric switch which controls the motor is connected in series with a pair of solenoid windings 26, 27 which are connected in parallel and which operate valves controlling the supply of fluid from a common source of pressure to means for operating a device-such as a motor car hood-in opposite directions, has a pair of switches 34, 35 provided for selectively connecting either of the valve operating windings together with the solenoid winding which operates the motor control switch to a source 10 of electrical energy.
